Disregard the custom logo. T3CH 8/27 + MC360 v.98691.
Upon accidental disconnection of ethernet and later reconnected.
The above problem can only be replicated if u,
Change the blade, then Go back to media Blade. Disconnect & reconnect the ethernet.

The above image was hosted on a slow server, wouldn't open sometimes. Here it is on Imageshack:

Maybe you should talk to the person that did your clear cache mod or better yet do a clean install of the skin and see if it still happens because I can see at least 3 mods in that xml file. The custom logo the clear cache and the temp down the bottem who knows what you screwed up doing them

Just to try, I did the same thing with a UNMODIFIED Mc360, same thing happens (Rarely).
Try this. Try Randomly unplugging the ethernet, while changing the blades or Stay on Movie Trailers button. Unplug and plug. There u will c it by yourself.

1 more intresting thing is that, once you start navingating through the panels, the seperator reappears.

Regarding the Clear Cache, its made my myself. [except for the actual script which does]
And the other is Temperature mod & Logo thing.

Ok maybe it does happen but honestly who keeps randomly unpluging there network cable

I have seen this as well but only on when I have added mods. Not seen it on official releases..

I would probably say that whoever did the mod needs to go and have another look at what he changed..
